This sort of thinking is based on the CPU being the only important part of a SoC. That may be true for your use cases, but it's not so for everyone.
While the CPUs on the M2 are reasonably characterized as you say, this is not true of the GPU.
It's probably not true of the NPU (though we don't yet have benchmarks).
It may well not be true of AMX (the patent trail suggests that AMX is evolving very rapidly to something like a competitor for AVX512, though it's never clear when a patent translates into a shipping product).
Even on the media side, it's probably the case that the M2 supports h.266 (at least decode), so that (just like Apple handled h.265) when they support the switchover to .266 as the preferred codec, there will already be a large installed base.
Bottom line is, right now all we have is quick benchmarks (like GB5) for CPU and some limited aspects of GPU. Until we get the full exploration (which, for M1, took many months) it's way too early to say.
